IMPROVIEMENT vIN BRIGK-MACHINES.

The Schedule referred to in these Itetters Patent and making part of the same.

reference being had to the accompanying drawing forming part ot' this specification.

This invention relates to improvement-s in brickmachines, whereby it is designed to provide a simple .and efficient airangementfor delivering the ground clay to the molds and pressing it therein, and for applying and removing the said molds, all as hereinafter more fully described.

. Figure l represents a sectional elevation, taken on the line x :l: of g. 2;

Figure 2 represents a t'rontelevation, partly broken and Figure 3 represents a plan of the mold-box.

Similar letters of reference indicate corresponding parts.

I arrange ar sliding presser, A, under the deliveringpassage B, leading from the bottom of the grindingmill at lone side ot' the same.-

This plunger' orpresser receives the ground clay in front, and forces it between the tapered dividing plates C into the mold-boxes E, set in front -of the said dividing-plates, which coincide in lengt-h, breadth, and position with thc dividing-walls D of the inoldboxes. v 1

The passage B. is regulated in capacity by a sliding gate, F, so as -to pass the` requisite quantity of clay for filling the molds at one movement of the plunger.

The clay receives two actions of the press, the tirst pressing it into the spaces between the dividing-plates, which narrow toward the rear, the second forcing itfrom the said spaces into the boxes, and supplying a fresh batch to the said spaces.

The presser' is operated by a. crank a-nd connectingrod, deriving motion from a wheel, H, rcaring with a spur-wheel, G, on the grinding-shaft.

The vgate F is moved by a crank-shaft, I, and pinions K thereon.

The mold-boxes E are placed on bearings or supports L, and clamped up snugly against the frame in front of the f lividing-plates C, to receive the clay by a hinged clampingiran1e, M, secured and held against the force of the plunger by spring catches N, which take over the top of the frame M'. t

A vertically-sliding knife, O, connected toa gate, 1, arranged in suitable ways, and provided with an opcratiug-hamlle, is provided, to be forced down between the mold-boxes and the dividing-plates C, to

separate the clay in the molds from that beyond, and y to shape the bricks on one'side.

When the lever Q of this knife-gate is pressed down, it strikes a stud of a spring rod, 1t, project-ing over a spring lever, S, ou the clamping-frame -.M, pressing it down and throwing up the tripping-levers T to disengagc the spring catches'N from the clamping-frame, to permit the mold-box to be removed for the substitution-of another. y

1t is intended that one set ot' molds shall be filled by one movement of the plunger, and this may be geared to work faster or slower', as required, the speed being limited only by the ability of the attendants to supply and remove the mold-boxes.

An alarm-spring, U, may be arranged to be sprung by the driving-pinion H at each revolution, for striking a blow at the proper time, to indicate when to move the cutter for separating the clay and disengaging the clamping-traine.

Having thus described my invent-ion,

What I claim as new, and desire to secure by Letters Patent, isf v 1T The combination with the clamping-frame of the trip-levers T, lever S, spring catches N, and spring pressing-rod R, when arranged substantially as speciiicd.

L. ln combination with the devices of the'above clause, the plunger or presser A and dividing-plates C, when arranged, constructed, and operating together, as herein shown and described. y
